Abstract (en)

[origin: EP3851825A1] A vibration control system, while applying Gaussian vibration that matches a reference vibration physical quantity PSD to a test object, makes a corresponding vibration physical quantity non-Gaussian. Using a response vibration physical quantity PSD and a reference vibration physical quantity PSD, a vibration physical quantity PSD for control is generated by a vibration physical quantity PSD calculator for control. A PSD convertor converts the vibration physical quantity PSD for control into a corresponding vibration physical quantity PSD for control in another dimension. Using the corresponding vibration physical quantity PSD for control, a corresponding vibration physical quantity waveform that is non-Gaussian, is generated by a corresponding vibration physical quantity waveform calculator for control. At least based on the equalization characteristics and the corresponding vibration physical quantity waveform for control, a drive waveform calculator generates a next drive waveform such that vibration that matches the corresponding vibration physical quantity waveform for control is applied to a test object.
